[PULL 02/28] tests/docker: Fix fedora-i386-cross cross-compilation

[Richard Henderson]

By using PKG_CONFIG_PATH instead of PKG_CONFIG_LIBDIR,
we were still including the 64-bit packages.  Install
pcre-devel.i686 to fill a missing glib2 dependency.

By using --extra-cflags instead of --cpu, we incorrectly
use the wrong probing during meson.
